Abstract (en)
The invention is a magnetic coupling device that utilizes a supported spherical magnet (20) to attach to a hole (24A) in a ferromagnetic object (23A). The hole shape and the orientation of the spherical magnet are predetermined to form a relatively strong magnetic attachment. The magnetic coupling device exhibits unique characteristics such as angular tolerance, precise positioning and controllable release characteristics.
